is there some way to make one option depend on another ?
ex

	[x] Enable Message Authentication

	   [.......] Enter Password Here

and "Enter Password Here" option would be grayed out
unless the top box is checked in.

The GTK's magic command to do is gtk_widget_set_sensitive().

However, is it possible to use it in Edit->Preferences->Protocol?

I see gtk_widget_set_sensitive() used in few places in Ethereal,
but none of them seem to be in context of the Protocols options.
